Vikas89 commented on issue #12255: Pretty high cpu load when import mxnet URL: https://github.com/apache/incubator-mxnet/issues/12255#issuecomment-444317987 There is huge number of threads getting created in operator-tune-inl.h that causes huge cpu load, threads take long time to determine whether they should use openmp for operator or not. This problem gets worse with machines with more cores. And multiplies with more processes. As an experiment if I change the omp parallelism to thread count 1, and launch 32 processes it just take 6 seconds to load.
